1. SRB @ CC-IN2P3 Jean-Yves Nief, CC-IN2P3 HEPiX, SLAC
October 11th – 13th, 2005

2. HEPiX Conference, SLAC, October 11th-13th 2005
Overview (I).
SRB not only used for BaBar.
Attractive for many projects:
Transparent interface with the Mass Storage System (MSS).
Easy administration of small files to be stored into the MSS (container = tar ball).
Interface with some existing relational database.
OS of your choice on each participating site.
Collaborative tool in order to share files:
ACL’s within groups, domains, zones, metadata, annotations.

7. Neuroscience research (II).
Goal: make SRB invisible to the end user.
More than 500,000 files registered.
Now interfaced within the MATLAB environment:
Data pushed where the CPUs are (CC-IN2P3, ENS Lyon).
~ 1.5 FTE for 3 months…
Next step:
Ever growing community (a few TBs / year).
Goal:
Join the BIRN network (US biomedical network).

8. HEPiX Conference, SLAC, October 11th-13th 2005
Summary.
Lightweight administration for the entire system.
Fully automated monitoring of the system health.
Doing user support for each project administrator.
Database:
Information system need to be performant.
Need to have a DBA.
Over 140 TB stored in SRB.
Over 1 million of files for some catalogs very soon.
More projects coming to SRB.
